Log:
[Clang][PowerPC] Support constraint 'wi' in asm
  From the gcc manual, we can see that the specific limit of wi inline asm is “FP or VSX register to hold 64-bit integers for VSX insns or NO_REGS”. The link is https://gcc.gnu.org/onlinedocs/gcc-8.2.0/gcc/Machine-Constraints.html#Machine-Constraints. We should accept this constraint.
